So, the soap on the left is a standard tried and true recipe that I love and everyone I know loves. The soap on the right is almost the same recipe (little less cleansing) and I added some grape wood charcoal powder to the base. I saved some of the uncolored soap and poured it on top and textured it after it gelled. I have done colored swirls before, but never layering. Nor had I tried texturing, or charcoal. Figured I would kill three birds with one stone.
I also destroyed my mold in the process of the black soap. I was attempting to make a linerless mold. However the soap refused to come out and the soap was worth more than the materials so I tore the mold apart instead of tearing the soap out. I am pleased with the results. I think next time I will stick to a lighter trace before I pour (I blended to a very thick trace so that the layers would not mix) because of some small bubbles I got in the soap that are noticeable against the bleak blackness of the bar. They are just noticeable in real life, but the photos make them very evident (due to the flash.)
Oh, I also was able to use the custom stamp I cast out of aluminum on the black soap too. It is a triskelion (lower right is the decal I used when making the sculpey positive before I cast it.) It is hard to see on the soap because I used my on camera flash to shoot the soap, so a lot of definition is lost.
